I see great deals on E-bay for those years, why is '07 left out? Is there a difference? Help? I am ready to buy!!

07+ got different grille design than 04-06 ones.
If I remember correctly, 07+ got slightly bigger grilles with rounder edges.
I love 07+ titanium grilles. I saw one on ebay for 04-06 models, but it didn't look great as oem titanium ones.
